Martin Demichelis: Manchester City sign Atletico Madrid defender

Manchester City have signed Atletico Madrid defender Martin Demichelis for a reported £4.2m.

Demichelis, 32, told City's website: "I am delighted to have joined City because I am still hungry for success and want to improve."

The Argentina international only joined the Spanish side from Malaga on a free transfer in July.

City need defensive cover with captain Vincent Kompany sidelined for several weeks with a groin injury.

Demichelis was allowed to leave Atletico because the Spanish top-flight side are set to sign 24-year-old Ajax defender Toby Alderweireld.

Demichelis played under City boss Manuel Pellegrini at Malaga and River Plate and featured at the 2010 World Cup in South Africa.

He added: "I have been in Europe for 11 years now and this was a great chance for me to play in the Premier League with such a big club.

"I don't think there'll be any problems in adjusting to life here."

Chilean Pellegrini, who took charge at the Etihad Stadium in June, had already spent almost £90m on four signings, with midfielder Fernandinho joining for £30m, winger Jesus Navas arriving for £14.9m and forwards Stevan Jovetic and Alvaro Negredo costing £22m and £20m respectively.
